Benefits of technology

Therefore, in the present invention, the equipment can provide an obesity reducing agent together with the aforesaid sonication. Such an agent can be of percutaneous or oral administration, or can be administered by injection. For example, a food such as mustard, or medicines such as capsaicin, capsaicinoids or sibutramine, which elevate one's body temperature and enhance thermogenesis, can be taken or administered. Such a rise in body temperature, in the long term, tends to increase thermal radiation towards the outside of the body and thereby enhances the burning of FFA, etc.
Thereby, a synergistic effect, such

Problems solved by technology

Recently adult (including Mammalian) diseases such as diabetes mellitus, hypertension, and vascular degeneration of brain and viscera have become serious problems.
However, it is a big problem that maintaining an exercise program is very difficult without ample time and strong will.
But such techniques have no scientific evidence

first embodiment

Next, the equipment of the present invention is explained while referring to FIG. 3. The equipment is composed of a bath 2 and an ultrasound applicator 5 disposed on the wall of the bath 2. The applicator 5 generates ultrasound energy by applying a high frequency voltage fed from a non-illustrated driving circuit, and sonicates the body through the warm water 1. In the sonication equipment shown in FIG. 3, a macroscopic nearly uniform acoustic field is formed, even though there are speckle-like irregularities locally below the wave length due to multiple reflections from the walls. In the equipment, sonication of nearly the whole body is attained. If the intensity is near an upper allowable level, the walls should be made non-reflective and local irregularities due to standing waves should be avoided.

second embodiment

Next, the equipment of the present invention is explained with reference to FIG. 4. The equipment is composed of water bath 10 containing warm water 1 and the ultrasound applicator 5 which is disposed on the bottom of the bath. A living body 9 contacts the warm water with a sponge provided as an elastic sealing member. At the bottom of the bath, a pipe 12 is provided to supply warm water 1 at constant pressure, wherein overflow is guided to the overflow container 13 through a non-illustrated overflow pipe, or alternatively, the water 1 penetrates through the sponge and is discharged out through the drain pipe 14. The applicator 5 generates ultrasound energy in a same manner as FIG. 3 and thereby sonicates the living body 6 through the warm water 1.

In the equipment shown in FIG. 4, the abdomen can contact an open water free surface without any air bubbles remaining.

It is desirable to monitor the water presence because transducers such as water-immersed types may be damaged by a lack ...

third embodiment

Next, the equipment of the present invention is explained with reference to FIG. 5.

The sonication method of prior art provided scanning along the body surface area by using a small transducer and interposing an acoustic coupling agent such as jelly. This is reasonable because irregularity of the near field due to interference can be averaged by such area scanning. But, in this method, some caution is required whenever a very definite threshold exists as shown in the aforesaid hemolysis. There can be some dangerous cases, such that biological phenomenon may jump non-linearly at a localized spot over the threshold intensity, even though its mean is still below the threshold. Therefore, when the near field is used, a high mean value near an allowable limit cannot be used. The use of far field thus is a solution. Also, the small sonication area of such a small transducer forces the operator to scan manually over a wide area. This is yet another defect.

The ultrasound applicator 15 shown ...

Abstract

This invention discloses an equipment for lipolysis of fat of a living body by ultrasound sonication. An effective ultrasound is characterized in low frequency 15-140 kHz region, by an intensity when in a range of 15-50 kHz, which is greater than 10 mw/cm2and below a hemolysis limit, and an intensity when in a range of 50-140 kHz, which is greater than 4 mW/cm2 and below the hemolysis limit or the safety level defined by MI. The invention is further characterized in a high frequency 180-1.3 MHz region, by an intensity when in a range of 180-700 kHz, which is greater than 10 mw/cm2 and below the safety level defined by M.I, and the intensity when in a range of 700 kHz-1.3 MHz, which is greater than 800 mw/cm2and below the safety level defined by MI.

Description

TECHNOLOGICAL FIELDThe present invention belongs to the field of equipment for reduction and prevention of obesity, and improvement of obesity for health and beauty, especially relating to ultrasound equipment for medical treatment and prevention of obesity and improvement of obesity for health and beauty.Recently adult (including Mammalian) diseases such as diabetes mellitus, hypertension, and vascular degeneration of brain and viscera have become serious problems. Their greatest origin is obesity.For improvement of obesity, it is known scientifically that suppression of caloric intake and exercise are effective. Administration of appetite suppressers and digestion / intake suppressers in addition to thermo-metabolism enhancers are under study and some of them are approved by the Government.As for exercise, persons tend to undertake dieting, walking, physical exercise, dancing, swimming, cycling, etc, due to a shortage of exercise resulting from sedentary occupations and the populari...
